This is my
portable battery charger built from a 5.5HP motor and a standard
automotive alternator. The motor & alternator are joined together
with a special built housing which has a flexible joint mounted on
the two shafts.
The motor runs
at about 2400rpm to produce 13.5volts continuously. You can run the
charger with equipment hooked up to your battery with out adverse
effects. Not as good as a portable generator but handy none the
less. This was built without any special tools in my garage.
